The final renewal day of this

eigure7-1: 1. One
kind of the water striders 2. The
place where many eggs of the water strider were found.

eigure7-2: The
eggs of the water strider (Gerris sp.) @The egg seen in the photograph is the
egg of the water strider that it lays eggs in the root of the plant which grew
in the surface of the water. I brought back this root to observe the egg of
Ischnura senegalensis. The egg-parasitoids wasp are in the blackish egg.

eigure7-3:The
eggs of the water strider (Gerris sp.) The egg that compound eyes look red is
the egg which a water strider hatches. It is the egg which an egg-parasitoids
wasp
parasitizes that compound eyes don't turn red. @The size of the egg:
1.35mm~0.55mm.

eigure7-4: 1. The
egg of the water strider which an egg-parasitoids wasp parasitized The egg which an
egg-parasitoids wasp parasitized becomes blackish. The inside of the egg isn't
transparent. Before an egg-parasitoids wasp emerges half of the egg becomes a little
transparent. 2. A round hole is made because an egg-parasitoids wasp bites off the
shell of the egg and comes out. 3. An egg with the oblong crack is the egg
which a water strider hatched.
